Another Question About Replacing the Battery

Dwight Frye

I did a search about replacing the battery and just want to double check before I get started. My '09 has almost 35K miles and I want to install a new battery as a preemptive measure against it failing in the next few months. I understand about lowering the windows first and the need to reset them after installing the new battery and to disconnect the negative cable first.

The Service Manual though has this whole section about ADDITIONAL SERVICE WHEN REMOVING BATTERY NEGATIVE TERMINAL : Required Procedure After Battery Disconnection (General Information PDF, Page GI-52) and references Automatic Temperature Control, several items related to it along with the Power Window Control System. What the heck is that all about ? Am I going to have to take it to the dealer for resets after I just swap out the battery ?
I was just assuming that the clock, maintenance reminder feature and radio stations would need to be reset along with the windows. What has other people's experiences been ?
Thanks
